Impaired Waters & 303(d) Lists
Under Section 303(d) of the CWA, states, territories, and authorized
tribes (referred to as 'states' below) are required
to develop, and update every two years, lists of waters - rivers,
lakes, coastal waters and estuaries - that are impaired (or threatened)
by one or more pollutants. Impaired waters are waters that do not
meet Water Quality Standards (WQSs) even after point sources of
pollution (e.g., municipal and industrial discharges) have installed
required levels of pollution controls. In addition to listing impaired
waters, each state prioritizes TMDLs for development.
States must consider "all existing and readily available
information" when developing their lists. Along with the list,
each state submits a listing methodology to EPA. At EPA's
request, states must provide "good cause" for not including
or removing a water from the list. To read the impaired waters lists
for New England states please go to the links below under "New
England State Pages."
EPA Listing Information:
EPA Approval Documentation for the New England States' Impaired
Waters/303(d) Lists
303(d) lists are organized by state and in chronological order,
with the most recently approved impaired waters listed first. The
tables will be updated continuously as lists are approved.
Many of the 303(d) list documents submitted to EPA by the States
appear in their TMDL or 303(d) list web pages (links in the table
below). Please note that the document that contains the 303(d)
list may be labeled “Integrated Report,” and that the
303(d) list itself may be found in an appendix part of the document.
